Abstract: (Elsevier)
In massive ø 4 theory two procedures are introduced that use the renormalization group to obtain an improved effective potential. This potential reduces to the ordinary effective potential for small excursions in field space and to the massless effective potential for large fields. Explicit results are given at the two-loop level.- phi**n model: 4
